Summary
👤
Senior🎓
Top SchoolZach Walker is a DLP optical design engineer with a PhD from BYU and 12 years of hands-on experience in micro/nanofabrication, optofluidics, silicon photonics, MEMS and semiconductor processes. He currently drives optical design at Texas Instruments while co-founding Laitus Solutions to commercialize a quick-install touchless drinking fountain sensor—demonstrating both product-focused entrepreneurship and cleanroom-to-market expertise. His doctoral work produced novel solid-state nanopore devices and uncovered a naturally forming 50 nm meniscus membrane, reflecting a knack for practical discovery and device innovation. Comfortable across simulation and code (Lumerical, Matlab, Python, C/C++), Zach has also contributed backend improvements to open-source tooling for code-coverage in production Ruby projects. Based in Dallas, he blends deep fabrication skills and systems-level optical engineering to move complex photonic concepts into manufacturable products.
